The challenge
Thin, debris-covered insulation over 864 sq ft
The inspection photos show the old insulation patchy across the deck, mixed with debris, and loose around the ducts. In that state it was doing little to keep heat out of the rooms below.
The job record called for the full sequence: remove, clean and sanitize, rodent-proof and air-seal, then insulate.
The service
The 5-step solution, in order
Prep and protection
Protective floor barriers laid through the work path before any material was moved, so the rest of the house stayed clean.
Remove the old insulation
All the existing insulation taken out with a heavy-duty vacuum across 864 sq ft, down to bare joists and a clear deck.
Clean and sanitize
Droppings, nests and debris vacuumed out, then OdoBan sanitation applied to neutralize odors and bacteria.
Seal and rodent-proof
Entry points closed with wire mesh, polyurethane foam and cement, with two to four indicator traps left as a check. Gaps around fixtures, piping, wiring and vents air-sealed in the same pass.
New insulation
New R-38 16in fiberglass batts installed across 864 sq ft, on a clean, sealed deck rather than on top of the old layer.
The result
864 sq ft of Pasadena attic, rebuilt in order
The attic finished with the old insulation removed, droppings, nests and debris vacuumed out, OdoBan sanitation, entry points sealed with wire mesh, polyurethane foam and cement, air sealing around fixtures, piping, wiring and vents, and new R-38 16in fiberglass batts across all 864 sq ft.

Questions homeowners ask
Attic work in Pasadena, answered
I need someone to clean my attic, seal the openings and fix the insulation in Pasadena. Who can do it?
Atticare USA handles all of it as one project. On this 91101 job the old insulation came out, the attic was cleaned and sanitized, entry points were sealed with wire mesh, foam and cement, gaps around fixtures and wiring were air-sealed, and new R-38 batts went in last.
What insulation does Atticare USA install in Pasadena attics?
It depends on the attic. This one got R-38 16in fiberglass batts; other Pasadena jobs have used blown-in cellulose. Either way it goes in after the old material is removed and the deck is cleaned and sealed, never on top of the old layer.
